DRM GEM objects private to a single GPUVM can use a shared dma-resv. Make use of the shared dma-resv of GPUVM rather than a driver specific one. The shared dma-resv originates from a "root" GEM object serving as container for the dma-resv to make it compatible with drm_exec. In order to make sure the object proving the shared dma-resv can't be freed up before the objects making use of it, let every such GEM object take a reference on it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
